Primary air setup
10.1. PRIMARY / SECONDARY AIR SETUP
For the regulation primary or secondary air use MANUAL PRIMARY /
SECONDARY AIR REGULATOR, (see Figure 8).
It is recommended to use the boiler to the factory defaults.
For a possible change in the setting of primary and secondary air is necessary to
remove the screw M5 (Figure 8).

3.0. MAKE UP AIR OPENING
Each boiler room must be equipped with an opening for supply of make up air
which is dimensioned in accordance with boiler output (minimum opening area
according to the below shown equation). Such opening must be protected with a net
or grate. All installation works have to be performed in accordance with valid
national and European standards. Boiler must not operate in flammable and
explosive environment.

4.0. CONNECTION TO CHIMNEY
Properly dimensioned and built chimney is a precondition for safe boiler operation
and heating efficiency. A chimney must be thermally insulated, gas-tight and
smooth. Cleaning door must be made in the lower part of a chimney. Chimney made
of bricks must include 3 layers with central insulation layer made of mineral wool.
Thickness of thermal insulation should be min. 30 mm of chimneys is built against to
interior wall, and min. 50 mm if it is built on the outer side. Internal dimensions of
the chimney light diameter depend on chimney height and boiler output and
they have to be selected in accordance with diagram shown in Figure 3. The
chimney usable height is the measure from connection spot of smoke pipe to the
chimney top. As these boilers can be fired with solid fuel, chimney has to be selected
according to the solid fuel diagram. Fuel gas temperature at the chimney exist must
be min. 30°C higher than condensation temperature of combustion gases.
Selection and building of a chimney must be made by a professional. Required
maximum distance from boiler to chimney is 1000 mm, and minimum distance is
500 mm. Uptake tube must be installed at an angle (min. 5°) with a gradient from
chimney to boiler (Figure 2). In order to prevent condensate from chimney to enter
the boiler, uptake tube must be placed 10 mm deeper into chimney. Connecting
uptake tube between boiler and chimney must be thermally insulated with a
mineral wool layer having thickness of 30 to 50 mm.
All installation works must be made in accordance with valid national and European
standards.
